When I use just
ffmpeg -f h264 -i input -vcodec copy -r 25 outfile.mp4
It replace initial IFrame with B-frames so I cannot playback it. I can view it with VCL, but not with Windows Media player, for example.
What is wrong with the command ?

ffmpeg concatenate image and audio to beginning of file
18 mai 2017, par swg1cor14So I want to try and use the ffmpeg MAP command to do the following :
Merge audio and jpg
Concatenate mp4 to endStill.jpg
audio.mp3 -> video.mp4 = output.mp4Right now I have
/home/admin/ffmpeg/ffmpeg -i still.jpg -i audio.mp3 render1.mp4
But I want to also go ahead and add on the video.mp4 as well. I tried reading the map function but I’m so confused as to how you know how many streams a file has, etc
Heres the output of the command....note I have different file names
